Sagot :
Answer:
Kyle sold 150 candy bars and Mary sold 75.
Step-by-step explanation:
the equation you want to use is 2x + x = 225.
the 2x is for Kyle and the x is for Mary.
then you can simplify to make it 3x = 225, divide both sides by 3 which gives you an x value of 75, and then you plug it into the original equation, which gives you:
2x + x = 2(75) + 75 = 225
